Chapter 16, Problem 128E

Interpretation Introduction

Interpretation:

The molecular mass of the compound, when $\text{11}\text{.2}\text{g}$ of the compound was dissolved in $2.80\times {10}^2\text{g}$ of water is to be stated.

Concept introduction:

Molality is defined as the measure of concentration of moles of solute in a solution. It is calculated by dividing the no. of moles of solute by the weight of solvent in $\text{Kg}$.

Colligative properties are defined as the physical properties of some dilute solutions which depend on the molal concentration of the solutes.
